ART OF PACKING INNER TUBES FOR PNEUMATIC TIRES Filed Jan. 4, 1930 Patented July 7, 1931 PATENT OFFICE JOHN COOPER, OF INCHINNAN, SCOTLAND j ART OF PACKING INNER- TUBES FOR PNEUMATIC TIRES Application filed January 4, 1930, Serial No. 418,544, and in Great Britain January 17, 1929.

This invention relates to the art of packing pneumatic tire inner tubes of the ringshaped type e. g, tubes of the type prepared on a ring-shaped mandrel, or moulded in a ring-shaped mould, and, when deflated, presenting when laid on a plane surface an annular ribbon.

Tubes of this type when folded diametrically with one half superimposed on the other may be coiled from one end into a roll having the configuration of a truncated cone.

The object of the invention is to provide a package comprising a tube of this type coiled into a conical roll and housed tightly ina hollow container of the same conicity as the roll, so that the surfaces of the roll and the container which are in frictional engagement are confined to the outer peripheral surface of the roll and the inner peripheral surface of the container.

In the drawings which illustrate the in vention diagrammatically Fig. 1 is a plan of a ring-shaped tube fully extended, Fig. 2 is a similar view showing the tube folded diametrically and partly rolled, and Fig. 3 a section showing the tube completely rolled and packed in a container.

The package shown comprises a tube 1 of the type described which is folded and coiled, as illustrated in Figs. 1 and 2, into a conical roll and housed tightly in a hollow container 2 having a base 3 and a lid 1 and being of the same conicity as the roll.

It will be seen from Fig. 3 that the surfaces of the roll and the container which are in frictional engagement are confined to the outer peripheral surface of the roll and the inner peripheral surface of the container.

The container is of hollow truncated conical formation and is of greater depth than the normal tube with which it is associated so that the end faces of the conically coiled tube 1 tightly fitted in the container are spaced from the base 3 and the lid 4;.

If desired, suitable packing material may be introduced between the tube and the lid so as to prevent endwise displacement of the tube relatively to the container.

The lid 4 and the base 3 are applied in known manner so as to render the package hermetically sealed and light-tight.

I claim 1. As an article of manufacture, a package comprising a ring-shaped pneumatic tire tube coiled into a conical roll, and a hollow container of truncated conical formation snugly housing said roll and being of the same conicity as said roll, so that the surfaces of said roll and said container which are in frictional engagement are confined to the outer peripheral surface of said roll and the inner peripheral surface of said container.

2. As an article of manufacture, a package comprising a ring-shaped pneumatic tire tube coiled into a conical roll, a hollow container oftruncated conical formation snugly housing said roll and being of the same conicity as said roll, so that the surfaces of said roll and said container which are in frictional engagement are confined to the outerperiplr eral surface of said roll and the inner peripheral surface of said container, and a base and a lid for said container positioned so as to be clear of the end faces of said roll.

3. As an article of manufacture, a package comprising a ring-shaped pneumatic tire tube coiled into a conical roll, a hollow container of truncated conical formation snugly housing said roll, said container being of the same conicity as, and being of greater depth than said roll, and a base and a lid for said container positioned near the ends of said container as to be spaced from the end faces of said roll.

4. As an article of manufacture, a package comprising a ring-shaped pneumatic tire tube coiled into a conical roll, a hollow container of truncated conical formation snugly housing said roll, said container being of the same conicity as, and of greater depth than said r611, so that the surfacesof said r011 and said'contain'er which are in frictional engage- 7 I v ment are confinedtojthe outer periphera1surface 7 of said roll and the inner peripheral surface of said container, and a base :anda lid for said container so positioned as to be space-dfrom the end faces ofsaid r0111, said basea'ndsaidlid forming with said co itainer e V name'to thls specificatlon.
